How to Meet the Capacity Challenge

Increase capacity efficiency of existing sites and equipment by redirecting the beam based on predictable customer traffic load. With this dynamic load balancing, traffic peaks are covered and the purchase of expensive new equipment can be delayed. There are up to three adjustments with SmartBeam antenna systems:

• RET Remote Electrical Tilt (Tilt)
• RAS Remote Azimuth Steering (Pan)
• RAB Remote Azimuth Beamwidth (Fan)

Free Yourself with SmartBeam Antenna Systems:

• Reduce OPEX by minimizing site visits
• Lower CAPEX by increasing capacity efficiency and delaying additional site builds
• Enhance network quality with the new ability to optimize the beam direction and width
• Experience fast, precise configuration updates
• Decrease inventory costs
• Prevent optimization implementation issues
• Generate fewer green house gases

With the three-way SmartBeam antenna, radio planners can now optimize the azimuth beamwidth itself, which is a revolution in network planning that results in significantly improved network quality.

Andrew Solutions offers three types of SmartBeam Antenna Systems, providing enhanced optimization options with easy and convenient execution, as well as excellent capacity efficiency through load balancing.

1-Way SmartBeam
Antenna (1D):

• RET Remote Electrical Tilt (typically, 0 to 10°)
• Fixed Azimuth Beamwidth
• Fixed Azimuth Steering

2-Way SmartBeam
Antenna (2D):

• RET Remote Electrical Tilt (typically, 0 to 10°)
• RAS Remote Azimuth Steering (+/ 30°)
• Fixed Azimuth Beamwidth

3-Way SmartBeam
Antenna (3D):

• RET Remote Electrical Tilt (typically, 2 to 10°)
• RAS Remote Azimuth Steering (+/ 30°)
• RAB Remote Azimuth Beamwidth (35° to 105°)

Load Balancing is a key factor for capacity efficiency. The red dots in the 3-sector site below show how uneven traffic distribution results in over loaded cells and under utilized sectors (left image below). The goal is to have even distribution of traffic, in all three sectors. By redirecting the beam (center image) and by further widening and narrowing the beam (right image). Traffic can be shifted from overloaded (yellow and blue) to under-utilized sectors (green), resulting in even traffic distribution and maximized capacity efficiency.

Uneven Traffic	Redirect The Beam	Widen/Narrow The Beam

With SmartBeam Antenna Systems, you can . . .

• Redirect the beam
• Widen/narrow the beam
• Shift traffic from overloaded to under loaded sectors
• Evenly distribute traffic to all sectors
• Significantly reduce sector overload
• Maximize utilization of sector capacity
• Improve capacity efficiency
